The Western Front was the main theatre of war during the First World War. Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France. The tide of the advance was dramatically turned with the Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trenches, stretching from the North Sea to the Swiss frontier with France, which changed little except during early 1917 and in 1918.

Explanation:
World War I is also known as "Trench Warfare" because of the way military operations were carried out. It covered the years 1915 and 1916. It was a consequence of the failure of the lightning war initiated by the Germans in 1914. It meant a change of strategy with respect to the preceding phase and opened the way to the war of stable fronts that immobilized the armies in trench lines which stretched over hundreds of kilometers, from the North Sea to Switzerland.
